Extremal

Penrose hypothesizes that the extremal is a graviton. ❋ Unknown (2005)

It is disingenious to ascribe every heat wave to global warming but explain away all extremal cold events as "just weather". ❋ Unknown (2010)

But at current and projected scientific abilities I cannot expect much more than what's offered – a collapsing extremal of baseline fundamental nature, even if there's no such thing as actually collapsed extremals. ❋ Unknown (2008)

If it works – even on a rudimentary level – Hameroff will be vindicated, and it won't matter at all that nobody knows what the extremal is. ❋ Unknown (2008)

I suspect there is some extremal principle here, where the tuning is some variational principle on a partition function which results in a greatest upper bound on the measure of complexity which can exist in a local region. ❋ Unknown (2010)

They calculated the entropy of black holes with electric charge, and in particular of extremal black holes — configurations where all of the energy really comes from the electric field itself, none from any purported mass that might have fallen into the black hole. ❋ Sean (2009)

We suggest that the unusual nature of this limit may help in understanding the entropy of extremal black holes. ❋ Sean (2009)

The best argument against it is the kind of microstate counting from string theory pioneered by Strominger and Vafa — they were always looking precisely at the extremal case, and found a non-zero entropy. ❋ Sean (2009)

And for an extremal black hole, they found an unusual answer: zero! ❋ Sean (2009)

In an extremal black hole, where all of the energy comes from the electric field itself, the two horizons coincide: we have r+ = r - (extremality). ❋ Sean (2009)

Perhaps the states disappear into Whoville, rather than really describing an extremal black hole. ❋ Sean (2009)

It certainly suggests a new angle on the behavior of the entropy: maybe HHR were right after all, and the entropy of a precisely extremal black hole really is zero — because the entropy that should be there has escaped into Whoville, this new anti-de Sitter spacetime that is a different part of the discontinuous limit. ❋ Sean (2009)

Green roof improves insulation because it reduces extremal temperatures on the roof during the year. ❋ Unknown (2007)

Most people (including, I think, the authors) believe that this result is not trustworthy, and reflects a breakdown of the particular method used, rather than a deep truth about extremal black holes. ❋ Sean (2009)

In other words, the approach to extremality is not continuous, as the non-extremal Reissner-Nordström solution splits into two spacetimes at extremality: an extremal black hole and a disconnected $AdS$ space. ❋ Sean (2009)

At the same time, desert is a system similar to the extremal habitats studied by space life support science since the mid 1950s, which are characterized by the availability of a powerful source of thermal energy and nearly complete absence of organic life and water (5, 6). ❋ Unknown (2009)

D ˆž to be the disjoint union of the function spaces Dn, for all n, except that the extremal elements are “glued together.” ❋ Bimbó, Katalin (2008)

Using the tools of extremal statistics, we analyze terrorist attacks worldwide between 1968 and 2004, as compiled in the National Memorial Institute for the Prevention of Terrorism (MIPT) database. ❋ Unknown (2005)

Let me try to make my argument in a rigorous fashion in arbitrary numbers of dimensions: We first assume that there is a fitness “surface” (a fitness function or set of (positive) fitness values, one for each point in phenotype space), and that even in the absence of feedback the function will have a number of local extremal values or “peaks”. ❋ Unknown (2007)

I had stubbornly insisted on equating Matti's multi-stage vector alignment for the extremal of consciousness as akin to the vector of a magnetic monopole. ❋ Unknown (2005)
